Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of paper products, in particular to a new type of composite high-strength three-dimensional paper card. Background Technique
[0002] Paper cards are a new type of paper card that is environmentally friendly. Their advantages of low cost and simple production are widely accepted and used. With the development of technology, by laminating paper, cardboard with other materials such as plastics, aluminum foils, cloth, etc., composite high-strength three-dimensional paper cards are made. Their good compressive strength has also been widely used in the packaging field and is suitable for various packaging needs.
[0003] There are still some problems in the use of existing composite high-strength three-dimensional paper cards. First of all, in order to facilitate the splicing of multiple paper cards to form a three-dimensional shape for users to protect objects during packaging, traditional paper cards are generally directly bonded and combined at the edges with adhesives. When subjected to external force impacts, the edges are prone to loosen and detach, resulting in low splicing and combination strength and poor durability. Secondly, in order to improve the compressive strength of traditional composite paper cards, some material combinations are relatively complex, which is not convenient for disassembly and recycling after use, reducing the use effect.
[0004] Therefore, we propose a new type of composite high-strength three-dimensional paper card to solve the above problems. Content of the Utility Model
[0005] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.
[0006] Therefore, the technical solution adopted by the utility model is as follows:
[0007] A new type of composite high-strength three-dimensional paper card, including multiple groups of outer protective sheathing plates. On the outer sides of multiple groups of the outer protective sheathing plates, two groups of second connecting card plates and two groups of first connecting card plates are symmetrically arranged respectively. Inside the two groups of the second connecting card plates and the first connecting card plates, inner extension embedding plates with one end embedded in the inner part of the outer protective sheathing plates are sleeved. At the corners where multiple groups of the outer protective sheathing plates are mutually clamped, abutting blocks that abut against each other are connected. On the inner side faces at both ends of multiple groups of the outer protective sheathing plates, two groups of inner support plates are symmetrically arranged. Two groups of extrusion embedding plates and sheathing card plates are respectively penetrated and embedded in the two groups of inner support plates. The extending end of the extrusion embedding plate penetrates through the inner extension embedding plate and is embedded and clamped with one end of the sheathing card plate. Inside the second connecting card plates and the first connecting card plates where the inner extension embedding plates are located, through locking rods are all penetrated and embedded.
[0008] The utility model can be further configured in a preferred example as follows:
[0009] By adopting the above technical solution, lock blocks are threadedly sleeved on the front and rear ends of the penetrating lock rod and located outside the second connecting card plate. One end of each abutting stop block is an inclined chamfered plane that fits against each other, and the other end of the extrusion panel is connected to one side end face of the abutting stop block.
[0010] In a preferred example, the present utility model can be further configured as:
[0011] By adopting the above technical solution, moving through holes are formed through the surfaces of the inner support plates close to the extrusion panels, and sliding connecting rods that are slidably clamped inside the moving through holes are connected to the outside of the extrusion panels.
[0012] In a preferred example, the present utility model can be further configured as:
[0013] By adopting the above technical solution, one end of the sleeved card plate is embedded and clamped on the inner end face of the outer protective sleeve plate, and an elastic rubber pad is embedded and filled at the clamping joint between the inside of the sleeved card plate and the extending end of the extrusion panel.
[0014] In a preferred example, the present utility model can be further configured as:
[0015] By adopting the above technical solution, one ends of the two groups of inner support plates are connected with multiple groups of extending inserts that are evenly embedded in the inner end face of the outer protective sleeve plate, and multiple groups of elastic rubber sleeves are evenly arranged between the other end faces of the two groups of inner support plates.

[0018] In a preferred example, the present utility model can be further configured as:
[0019] By adopting the above technical solution, multiple groups of connecting struts are embedded and connected between multiple groups of the elastic rubber sleeves.
[0020] By adopting the above technical solution, the beneficial effects achieved by the present utility model are:
[0021] 1. In the present utility model, by providing a first connecting clamping plate, a second connecting clamping plate, an inner extending embedding plate, a squeezing embedding plate, a sleeved clamping plate and an abutting stop block, during use, the inner extending embedding plate is embedded into a plurality of outer protective sleeve plates through the first connecting clamping plate and the second connecting clamping plate, and through the extrusion of the abutting stop block on the squeezing embedding plate, it is embedded and clamped with the sleeved clamping plate, and the inner extending embedding plate is squeezed and locked.

Such a combined and spliced structure not only ensures the compressive strength, but also facilitates subsequent disassembly and recycling, improving the use effect. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that, without conflict, the embodiments of the present utility model and the features in the embodiments can be combined with each other.
[0029] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model.
[0030] The following describes a new type of composite high-strength three-dimensional paper card provided by some embodiments of the present utility model with reference to the accompanying drawings.
[0031] Embodiment 1:
[0032] Combined with Figures 1 - 3 As shown, a new type of composite high-strength three-dimensional paper card provided by the present utility model
[0033] Specifically, it includes multiple groups of outer protective sheathing plates 1. On the outer sides of the multiple groups of outer protective sheathing plates 1, two groups of second connecting card plates 3 and two groups of first connecting card plates 2 are symmetrically arranged respectively. Inside the two groups of second connecting card plates 3 and first connecting card plates 2, inner extension embedding plates 11 with one end embedded inside the outer protective sheathing plates 1 are sleeved. At the corners where the multiple groups of outer protective sheathing plates 1 are mutually clamped, abutting stop blocks 5 that are mutually abutted are connected. On the inner side faces at both ends of the multiple groups of outer protective sheathing plates 1, two groups of inner support plates 6 are symmetrically arranged. The two groups of inner support plates 6 respectively penetrate and are embedded with an extrusion embedding plate 14 and a sheathing card plate 15. The extending end of the extrusion embedding plate 14 penetrates through the inner extension embedding plate 11 and is embedded and clamped with one end of the sheathing card plate 15. Inside the second connecting card plate 3 and the first connecting card plate 2 where the inner extension embedding plate 11 is located, a through locking rod 12 is penetrated and embedded. On the outer sides of the front and rear ends of the through locking rod 12 located outside the second connecting card plate 3, locking blocks 4 are threadedly sleeved. One ends of the abutting stop blocks 5 are inclined chamfered planes that are mutually attached. The other end of the extrusion embedding plate 14 is connected to one side end face of the abutting stop block 5. On the side of the inner support plate 6 close to the extrusion embedding plate 14, moving through holes 18 are through-opened. The moving through holes 18 are mainly used to facilitate the stable movement of the sliding connecting rod 16 to drive the extrusion embedding plate 14 and prevent the deviation of the position. A sliding connecting rod 16 that is slidably clamped inside the moving through hole 18 is connected to the outside of the extrusion embedding plate 14. One end of the sheathing card plate 15 is embedded and clamped with the inner side end face of the outer protective sheathing plate 1. An elastic rubber pad 17 is embedded and filled at the clamping position of the extending end of the extrusion embedding plate 14 inside the sheathing card plate 15. The elastic rubber pad 17 is mainly used for wear-resistant protection of the extending end of the extrusion embedding plate 14 to prevent mutual wear with the sheathing card plate 15. Through the use of the above-mentioned various components, the inner extension embedding plate 11 inside is embedded into the multiple groups of outer protective sheathing plates 1 through the first connecting card plate 2 and the second connecting card plate 3, and the extrusion embedding plate 14 is extruded by the abutting stop block 5 so that it is embedded and clamped with the top end of the sheathing card plate 15, and the inner extension embedding plate 11 is extruded and locked. With the through locking of the through locking rod 12 at the mutually clamped position of the inner extension embedding plate 11, the connection strength at the splicing and combination joints of the paper card is improved, preventing detachment and improving durability.
[0034] Embodiment 2:
[0035] Combined with Figure 1 and Figure 2As shown, on the basis of the first embodiment,
[0036] Specifically, one end of two groups of inner support plates 6 is connected with a plurality of extension inserts 7 evenly embedded in the inner end face of the outer protective sleeve plate 1. Between the other end faces of the two groups of inner support plates 6, a plurality of elastic rubber sleeves 8 are evenly arranged. A telescopic gasket 9 is sleeved inside the plurality of elastic rubber sleeves 8. The elastic protection of the telescopic gasket 9 and the elastic rubber sleeves 8 provides elastic protection for the support cardboard 10, enhancing the compressive effect. The support cardboard 10 is sleeved inside the telescopic gasket 9. A plurality of connecting struts 13 are embedded and connected between the plurality of elastic rubber sleeves 8. The connecting struts 13 are mainly used to facilitate the installation and connection of the elastic rubber sleeves 8. The use of the above components and the components in the first embodiment is as follows: by loosening the through-lock rod 12 through the lock block 4, and at the same time separating the extrusion insert plate 14 from the inner extension insert 11 and the sleeve clamping plate 15 through the abutting stop block 5, the combined whole of the connecting struts 13, elastic rubber sleeves 8, telescopic gaskets 9 and support cardboard 10 inside the outer protective sleeve plate 1 is moved out of the outside of the outer protective sleeve plate 1, and it is convenient to move the two groups of inner support plates 6 out of the outside. The combined and spliced structure ensures the compressive strength and is convenient for subsequent disassembly and recycling.
[0037] The working principle and usage process of the present utility model are as follows: First, when in use, in order to splice and combine a plurality of outer protective sleeve plates 1 to package and protect an object, the inner extension inserts 11 inside can be embedded into the inside of the plurality of outer protective sleeve plates 1 through the first connecting card plate 2 and the second connecting card plate 3, and the abutting stop blocks 5 at the corners of the plurality of outer protective sleeve plates 1 are mutually butted and abutted, and the extrusion insert plate 14 is extruded, so that its extending end is embedded and clamped with the top end of the sleeve clamping plate 15, and is in close contact with the elastic rubber pad 17, and the inner extension insert 11 is extruded and locked. At the same time, the through-lock rod 12 also penetrates and locks the mutually clamped parts of the inner extension inserts 11 of the first connecting card plate 2 and the second connecting card plate 3. This not only improves the splicing and combination strength of the paper cards, but also prevents separation and improves the overall durability. Secondly, when in use, through the use of the above components, especially the loosening of the through-lock rod 12 through the lock block 4, including the separation of the extrusion insert plate 14 from the inner extension insert 11 and the sleeve clamping plate 15 by the abutting stop block 5, the combined whole of the connecting struts 13, elastic rubber sleeves 8, telescopic gaskets 9 and support cardboard 10 combined inside the outer protective sleeve plate 1 is moved out along the two groups of inner support plates 6. Finally, the two groups of inner support plates 6 lose the supporting force, and the plurality of extension inserts 7 are loosened from the inner end face of the outer protective sleeve plate 1, which is convenient to move the inner support plates 6 out of the outside. Such a combined and spliced structure not only ensures the compressive strength, but also is convenient for subsequent disassembly and recycling, improving the use effect.
[0038] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
